I dont think any canceallation would occur, because that would imply
that one of them has a component projected into the other's space.
I can see a frequency addition taking place (as the vector sum
increases because the two signals are orthogonal) but I cannot see a
subtraction.
I might be mistaken here though.
Look at the sine and cosine as an example, the amplitude of their sums
(or difference) is always bigger than their individual components.
